Detailed description of the invention

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention Formula is described in further detail.

Before the embodiment of the present invention is carried out detailed explanation, first the application scenarios of the embodiment of the present invention is given Introduce.The method that the embodiment of the present invention provides is applied to terminal, and this terminal is armarium in medical treatment scene, and this armarium can Think the display device of medical image, as computer, CT (Computed Tomography, CT scan) machine, Nuclear magnetic resonance analyser etc., this medical image can be two-dimensional medical images, 3 D medical reconstruction model etc., and the embodiment of the present invention is to this Do not limit.In the medical scene of the sterility requirements such as operation, doctor can be by the light on gesture operation control terminal display interface Mark, to move the cursor to the target location on medical image, and moves medical image, rotates or scaling etc. is adjusted Whole, thus avoid the physical contact between terminal, meet the sterility requirements of medical treatment scene.Further, this armarium is extremely There is display function less, for showing the image of such as two dimensional image, threedimensional model etc., it is possible to carry in current display interface For a cursor；It addition, this terminal also has gesture identification function, the gesture of user can be identified, it is possible to according to user's Cursor in display interface is moved by gesture, example, and this terminal can obtain user's by shooting or infrared technique Gesture, and the gesture of user is identified, this is not limited by the embodiment of the present invention.

Figure 1A is a kind of based on gesture the cursor-moving method flow process shown for medical treatment that the embodiment of the present invention provides Figure, sees Figure 1A, and the method can include following several step:

Step 101: receive the 3rd operational order.

Wherein, the 3rd operational order presets grid and cursor for instruction display in current display interface.3rd Operational order can be triggered by certain physics hardkey of this terminal, it is also possible to the 3rd gesture made by this terminal recognition to user Trigger, wherein, it is preferred that the 3rd gesture that the 3rd operational order is made by this terminal recognition to user triggers, and can effectively keep away Exempt from the physical contact between doctor and terminal, meet the sterility requirements of medical operating scene.The concrete sign-shaped of the 3rd gesture Formula can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.Such as, the 3rd hands Gesture can be the gesture rocking a finger, the gesture clenched fist or the gesture etc. opening palm.

Step 102: show default grid and the cursor of first resolution, and described cursor is positioned at the knot of described default grid On point.

After this terminal receives the 3rd operational order, its current display interface shows the default grid of first resolution And cursor, and cursor is positioned on the node of this default grating image.It should be noted that the default grid of this first resolution is Obtaining based on current display interface drafting, it includes multiple grid, meanwhile, for ensureing cursor mobile step in each direction Long the most identical, being sized and shaped to of each grid is identical.For the concrete shape of each grid, the embodiment of the present invention Not limiting, example, the shape of each grid can be triangle, rhombus, square and rectangle, wherein, it is preferred that pre- If each grid in grid is square, square can ensure that the distance in default grid between the most adjacent two nodes Identical, i.e. ensure that cursor moving step length in each direction is identical.

Wherein, cursor, for indicating the position of operation focus in current display interface, can be marked on by mobile light Position in current display interface realizes operation focus movement in current display interface.Cursor for the embodiment of the present invention Shape, color and display pattern can be by terminal default setting, it is also possible to by user setup, this is not done by the embodiment of the present invention Limit.Example, this cursor can be cross-hair icon as shown in Figure 1B.

In the embodiment of the present invention, before receiving the 3rd operational order, the grid display function of this terminal is not opened, Showing pending medical image in its current display interface, grid is not preset in display.And show when user wants to start grid When showing function, example, the 3rd gesture can be made in the range of the gesture identification of this terminal, when this terminal recognition to the 3rd During gesture, trigger the 3rd operational order, and then in the current display interface of this terminal, show the default grid of first resolution And cursor.For example, with reference to Fig. 1 C, before recognizing the 3rd gesture, the current display interface of this terminal only shows liver Organic image, and when recognizing three gestures, see Figure 1B, this terminal can demonstrate first point in current display interface The default grid of resolution and cursor.

It should be noted that before grid display function on, this current display interface can show cursor, also Can not display highlighting, this is not limited by the embodiment of the present invention.Specifically, if before grid display function on, should Current display interface does not shows cursor, then the 3rd operational order can serve to indicate that display the on display interface in this prior The default grid of one resolution and cursor, and if grid display function on before, this current display interface shows Cursor, then the 3rd gesture can be only used for indicating the default grid showing first resolution on display interface in this prior, and Ensure that this cursor shows on the node of this default grating image.

Further, in order to improve display effect, the display layer of default grid can be arranged on pending medical science shadow On the display layer of picture, that is to say that, when default grid is overlapping with pending medical image, default grid is displayed on this and waits to locate Above reason medical image figure layer；Further, it is also possible to light target display layer is arranged on the display layer of default grid, from And when cursor is overlapping with default grid, cursor is displayed on above the figure layer of this default grid.So, so that user relatively For it can be clearly seen that default grid and light target move.Additionally, for the display effect improving pending medical image, can be by Pending medical image display layer is arranged on display layer and the light target display layer of default grid, certainly, be the most only away from From explanation, do not represent and the present invention is limited to this.

It should be noted that this terminal can show in whole display interface presets grid, it is also possible to only in its local In display interface, grid is preset in display, and this is not limited by the embodiment of the present invention.

Specifically, the display interface of this terminal shows default grid and the light target process of first resolution, permissible Including any one in following two mode:

The first implementation: determine the first specified point；Centered by described first specified point, specify ratio according to first Example, determines that the length of side that the first grid viewing area, described first designated ratio are described first grid viewing area is aobvious with described Showing the ratio between the corresponding length of side at interface, described first designated ratio is less than or equal to 1；According to first resolution, described In first grid viewing area, grid is preset in display；Determine the display position that described light is marked on described default grid, and show Described cursor.

It should be noted that first resolution is for indicating default grid length side in this first grid viewing area Grid number on grid number upwards and width, that is to say that first resolution is big for the grid indicating default grid Little.

Wherein, this first specified point can be any point on this display interface, example, and this first specified point can be With the center of display interface at a distance of the location point of distance to a declared goal, it is also possible to for the central point etc. of this display interface, it is preferred that this is the years old One specified point is the central point of this display interface.When the central point that this first specified point is this display interface, with this first finger The default grid built centered by fixed point is also displayed on the central area of this display interface, it is possible in this display interface Heart point shows this cursor, will be arranged on this first specified point by light target initial position, so that cursor can be quick Move to the arbitrary region of this display interface, it is simple to cursor quickly navigates to arbitrary target position, i.e. be easy to operation focus quick Navigate to arbitrary target position.

Wherein, this first grid viewing area is the region showing this default grid, is used for indicating this default grid to show The size in region.First grid viewing area can be determined by the first designated ratio, is the display interface of this terminal by this The region that first designated ratio reduces, therefore each side length of this first grid viewing area is this display interface by this The side length that first designated ratio reduces.Wherein, this first designated ratio can be by terminal default setting, it is also possible to by user Arranging, such as this first designated ratio can be set to 1,1/2,1/3,1/4 etc. by terminal, and this is not limited by the embodiment of the present invention Fixed.

As a example by a length of W of display interface, width are as H, then this display interface can represent with W × H, when first specifies When ratio is 1, seeing Figure 1B, this terminal can show in the display interface of whole W × H presets grid, correspondingly, the first grid The size of lattice viewing area is W × H；When the first designated ratio is 1/3, seeing Fig. 1 D, this terminal can show with it Centered by the central point at interface, and in the rectangular area that a length of W/3, width are H/3, show this default grid, correspondingly, the The size of one grid viewing area is W/3 × H/3.Wherein, in Figure 1B-Fig. 1 F, less cross-hair icon represents that user thinks Target location to be navigated to, bigger cross-hair icon represents that cursor, the cross-hair icon in Fig. 1 F then represent cursor.

Wherein, showing in this first grid viewing area and preset during grid, this terminal can be according to default the One resolution, carries out each length of side of this first grid viewing area decile, thus obtains the default grid of this first resolution Lattice.Wherein, first resolution can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention Fixed.Example, this first resolution is less than the pixel resolution of this first grid viewing area, this first grid viewing area Pixel resolution for the pixel number indicated in this first grid viewing area on length direction and width Pixel number.

It should be noted is that, this first resolution refer to be in advance first grid viewing area arrange default grid Resolution, for indicating this default grid grid number on the first grid viewing area length direction and width Grid number, and this default grid grid number on the first grid viewing area length direction and the grid on width Lattice number can be identical, it is also possible to different, this is not limited by the embodiment of the present invention.For the ease of describing, next will be with this As a example by default grid grid number on the first grid viewing area length direction is identical with the grid number on width Illustrate.

Example, this first resolution can be expressed as:

R_n=(2⁽ⁿ⁺¹⁾, 2⁽ⁿ⁺¹⁾), (n ∈ (0, N-1)) (1)

Wherein, R_nFor first resolution, first 2⁽ⁿ⁺¹⁾Represent that this default grid is in the first grid viewing area length side Grid number upwards, second 2⁽ⁿ⁺¹⁾Represent this default grid grid number on the first grid viewing area width Mesh, and the lower limit of first resolution is (2,2), the upper limit is (2^N, 2^N)。

Or, this appointment raster resolution can also be expressed as:

R_n=(2⁽ⁿ⁺²⁾, 2⁽ⁿ⁺²⁾), (n ∈ (0, N-2)) (2)

Wherein, R_nFor first resolution, first 2⁽ⁿ⁺²⁾Represent that this default grid is in the first grid viewing area length side Grid number upwards, second 2⁽ⁿ⁺²⁾Represent this default grid grid number on the first grid viewing area width Mesh, and the lower limit of this appointment raster resolution is (4,4), the upper limit is (2^N, 2^N)。

In above two representation, N all can determine according to the pixel resolution of this first grid viewing area.Example As, when the pixel resolution of this first grid viewing area is (X, Y), i.e. in this first grid viewing area on length direction Pixel number be the pixel number on X, width when being Y, then 2^N< min (X, Y).

In above-mentioned representation, the size of first resolution can be set by the size arranging n.Such as, with this As a example by terminal uses formula (2) to represent first resolution, when n is set to 0, this first resolution is (4,4), this terminal Can show as shown in Figure 1B and Fig. 1 D 4 × 4 default grid.

It addition, for the ease of cursor mobile on default grid, this cursor can be arranged on the node of default grid, And this cursor may be located at any site position on default grid, this is not limited by the embodiment of the present invention.Example, permissible Being arranged on by this cursor at arbitrary grid intersection of default grid and (i.e. preset the arbitrary node position of grid), such as cursor is arranged In the central node of default grid, if or cursor be arranged on the grid knot that distance presets the central node dry lattice number of grid On point, it is preferred that cursor is arranged on the central node of default grid so that this light is marked on any direction of default grid all to be had There is bigger mobile range.

Needing explanation on the other hand, the embodiment of the present invention is only to show default grid and the cursor of first resolution During, first show the default grid of first resolution, then determine cursor on the node of the default grid of first resolution Display position, example, with the central node of the default grid of first resolution be this light target show position.Certainly, also Can directly using the first specified point as light target initial display position, i.e. before the default grid of display first resolution, Showing this cursor at the first specified point, this is not limited by the embodiment of the present invention.

The second implementation: determine described smooth target position on display interface；Centered by described smooth target position, press According to the first designated ratio, determine that the first grid viewing area, described first designated ratio are described first grid viewing area Ratio between the length of side and the corresponding length of side of described display interface, described first designated ratio is less than or equal to 1；According to first point Resolution, in described first grid viewing area, grid is preset in display.

Under this kind of mode, before the default grid of display first resolution, this display interface can display highlighting.Its In, this cursor can give tacit consent to display appointment position on this display interface before receiving the 3rd operational order, it is also possible to Position is shown by this light target of user setup.Example, user can indicate any position of this display interface with finger, thus Control terminal and cursor is shown, and this is not limited by the embodiment of the present invention in the position of user's finger instruction.

Afterwards, when receiving three operational orders, this terminal can first determine this light target position on this display interface, Thus centered by this light target position, in the first grid viewing area, show the default grid of first resolution.

Wherein, according to the first designated ratio, determine the detailed process of the first grid viewing area, and differentiate according to first Rate, in this first grid viewing area, the detailed process of grid is preset in display, is referred to the first implementation above-mentioned Associated description, the embodiment of the present invention does not repeats them here.

Step 103: receive the first operational order.

Wherein, the default grid that this first operational order shows in its current display interface for indicating terminal moves The cursor that its current display interface shows.The first gesture that this first operational order is made by terminal recognition to user triggers, can With the physical contact being prevented effectively between doctor and terminal, meet the sterility requirements of medical operating scene.The tool of this first gesture Body gesture form can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.Such as, This first gesture can be that user stretches out that a finger makes click action, upper paddling is made, lower paddling is made, left paddling is made and right draws Action, certainly, is merely illustrative of herein, and the first gesture not representing the embodiment of the present invention is confined to this.

Further, in order to improve the operability of user, this first gesture can be the gesture that an amplitude is bigger, and Can there is certain gesture error, as long as user makes this first gesture in range of error, this terminal can recognize this First gesture, and then trigger the first operational order.Such as, as long as user makes the right side in the range of 10 ° with horizontal direction angle During oarsman's gesture, this terminal can recognize this right oarsman's gesture, and then triggers the first operational order.

Step 104: when the displacement of first object is more than the first predetermined threshold value, described cursor moves on the display screen The default grid of dynamic predetermined number.

After terminal receives the first operational order, start to detect the displacement of first object and moving direction.Need It is noted that first object could be for controlling light and is marked on any motive objects of movement on the default grid of display screen Body, example, the transportable object such as the scalpel in the finger of such as user, fist or user's hands, the present invention implements This is not limited by example.Preferably, using user's finger of aloft moving as first object, it is used for controlling light and is marked on display screen Move on the default grid of curtain, example, user thrusts out one's fingers paddling aloft, and then, according to user's finger paddling aloft Direction and displacement, control light and be marked on the default grid of display screen and move.Because user's finger motion is flexibly and user's hands Refer to as first object, the detection data volume of terminal can be reduced, improve processing speed and the response speed of terminal.

During first object moves, detection that terminal is real-time and obtain displacement and the movement side of first object To, wherein, the moving direction of first object includes upper and lower, left and right, upper left, upper right, lower-left and bottom right, the movement of first object Distance includes the distance of above-below direction and the distance of left and right directions.

Example, if the moving direction of first object is up or down, then the movement of the first object got away from From the distance for above-below direction；If the moving direction of first object is to the left or to the right, then the shifting of the first object got The distance that dynamic distance is left and right directions；If the moving direction of first object is to upper left, to upper right, to left down or to bottom right, The displacement of the first object then got is distance and the distance of above-below direction of left and right directions.

Further, after displacement and the moving direction of first object being detected, it is judged that the movement of first object away from From whether more than the first predetermined threshold value, wherein, if the displacement of first object is more than the first predetermined threshold value, along first object Moving direction, the grid of mobile predetermined number on the default grid that cursor is shown on the display screen.

It should be noted that this first predetermined threshold value can be by terminal default setting, it is also possible to by user setup, the present invention This is not limited by embodiment.Example, this first predetermined threshold value can be 5mm, 10mm etc..

It should be noted that light be marked on default grid mobile during, light is marked between the node of default grid and moves, Wherein, presetting the node of grid is to preset in grid the intersection point between ruling vertically and horizontally.Example, can limit Determine cursor only to move on the upper and lower, left and right four direction of default grid, i.e. cursor can not be directly at the diagonal angle of default grid Line side moves up, when cursor needs from the node motion of the default grid diagonal institute to a grid of default grid Node, cursor needs first to move a node in left-right direction, then moves to this node along the vertical direction, certainly in this mistake Cheng Zhong, cursor can also move a node the most along the vertical direction, then arrive this node mobile, the embodiment of the present invention in left-right direction This is moved order do not limit.Only move on the upper and lower, left and right four direction of default grid by limiting cursor, thus Define light target degree of freedom, improve the accuracy that cursor moves.

Concrete, after moving direction and the displacement of first object being detected, if the moving direction of first object is Up or down, then judge whether the displacement of the above-below direction of the first object got is more than the first predetermined threshold value, as Really the displacement of the above-below direction of first object be more than the first predetermined threshold value, then light is marked on default grid along upwards or to Lower direction, the grid of mobile predetermined number, i.e. light are marked on default grid the knot moving predetermined number along direction up or down Point；If the moving direction of first object is to the left or to the right, then judge the movement of the left and right directions of first object that gets away from From whether more than the first predetermined threshold value, if the displacement of the left and right directions of first object is more than the first predetermined threshold value, then will Light is marked on default grid along direction to the left or to the right, and the grid of mobile predetermined number, i.e. light are marked on default grid along to the left Or right direction moves the node of predetermined number.

Further, if the moving direction of first object is to upper left, to upper right, to left down or to bottom right, then judge to obtain Whether the displacement of the left and right directions of the first object got and the displacement of above-below direction are more than the first predetermined threshold value, as Really the displacement of the above-below direction of first object be more than the first predetermined threshold value, then light is marked on default grid along upwards or to Lower direction moves to the node of predetermined number；If the displacement of the left and right directions of first object is more than the first predetermined threshold value, Then light is marked on default grid the node moving to predetermined number along direction to the left or to the right；If the upper and lower of first object To displacement and the displacement of left and right directions be all higher than the first predetermined threshold value, then light is marked on default grid along first The moving direction of target, moves the grid of predetermined number along the diagonal presetting grid.It should be noted that again by cursor Along the moving direction of first object on default grid, during moving to the next node that diagonal is corresponding, Ke Yixian Move a node in left-right direction, then move to this node along the vertical direction, it is also possible to first move a knot along the vertical direction Point, then arrive this node mobile in left-right direction, it is of course also possible to do not show above-mentioned moving process, directly display cursor from currently Node moves to the next node that diagonal is corresponding, and this is not limited by the embodiment of the present invention.

It should be noted is that, in the embodiment of the present invention, after receiving the first operational order, step 104 is probably The process that one circulation performs.That is to say, during record first object displacement, when the movement determining first object When distance is more than the first predetermined threshold value, cursor moves the grid of predetermined number on the display screen, and this grid is big for presetting grid Little, afterwards, the displacement of first object recorded can be reset by this terminal, and continue the movement recording first object away from From, when the displacement again determining recorded first object is more than the first predetermined threshold value, light rotating savings is at display screen On move the grid of predetermined number again, such that it is able to during first object continuous moving, repeatedly move cursor, i.e. basis The displacement of first object and moving direction, it is achieved by cursor default grid on the display screen, move from primary importance Move the second position.

Example, if predetermined number is 3, and the first predetermined threshold value is 10mm (millimeter), when user's finger paddling to the right During 30mm (millimeter), may move right 9 nodes, i.e. cursor of cursor have moved right the grid of 3 predetermined numbers.

Example, when the moving direction of first object be level to the right, and determine that the displacement of first object is more than the During one predetermined threshold value threshold value, see Fig. 1 E, grid node in this prior can be moved to right by cursor at current grid node At the node of side and distance current node predetermined number grid.Example, user moves by continuous horizontal to upper right side One target, moves to preset as shown in Figure 1 F the upper right corner of grid by cursor from the center of the default grid shown in Fig. 1 E Position.

It should be noted that predetermined number is greater than the integer of 1, predetermined number is the biggest, and light is marked on the control of first object Under, the translational speed on default grid is the fastest, and the jumping characteristic of moving process is the biggest, it is preferred that predetermined number is little more than 1 In the integer of 10.Wherein, predetermined number can be by terminal default setting, it is also possible to by user setup, the embodiment of the present invention is to this Do not limit.

Need explanation on the other hand, when default raster resolution is identical, but during predetermined number difference, the shifting of first object Dynamic distance is more than the first predetermined threshold value, and the light that cursor moves the grid of predetermined number corresponding on the display screen is marked on display screen The distance of upper actual movement differs.Concrete, predetermined number is the biggest, and cursor moves presetting of the first resolution of predetermined number The distance of the actual on the display screen movement that grid is corresponding is the biggest；Predetermined number is the least, and cursor moves the of predetermined number The distance of the actual on the display screen movement that the default grid of one resolution is corresponding is the least.Therefore, first object move away from From more than the first predetermined threshold value, the size of the actual displacement of cursor, can be by regulation predetermined number Size is adjusted.

Step 105: receive the second operational order.

Wherein, the second operational order is for indicating terminal to change the size of predetermined number.This second operational order is by terminal Recognize the second gesture triggering that user makes, the physical contact between doctor and terminal can be prevented effectively from, meet medical treatment hands The sterility requirements of art scene.The concrete gesture form of this second gesture can be by terminal default setting, it is also possible to by user setup, This is not limited by the embodiment of the present invention.Such as, this second gesture can be user from the state of clenching fist become the five fingers extended state, Or become extended state etc. for thumb forefinger and middle finger three from closure state, certainly, be merely illustrative of, not herein The second gesture representing the embodiment of the present invention is confined to this.

Step 106: when the distance of described cursor to target location is less than the second predetermined threshold value, reduces described first and presets The described predetermined number that threshold value is corresponding.

Concrete, after terminal receives the second operational order, change the predetermined number that the first predetermined threshold value is corresponding Size, and then by changing the size of predetermined number corresponding to the first predetermined threshold value, it is achieved change the movement of first object away from Size from the distance that corresponding cursor moves on the display screen.

It should be noted is that, after terminal receives the second operational order, the first predetermined threshold value can be increased corresponding Predetermined number, it is also possible to reduce the predetermined number that the first predetermined threshold value is corresponding；Wherein, the scaling up of predetermined number and reduction Ratio can have terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.

Needing explanation on the other hand, user can constantly make second gesture, and then repeatedly triggering the second operation refers to Order, it is achieved the size of the predetermined number that the most continuous first predetermined threshold value of terminal is corresponding, until adjusting to customer satisfaction system the Till the size of the predetermined number that one predetermined threshold value is corresponding, this is not limited by the embodiment of the present invention.

Example, the initial value of the predetermined number that the first predetermined threshold value is corresponding is 3, after receiving the second operational order, The initial value of predetermined number corresponding for the first predetermined threshold value is reduced 1 by terminal, the present count quantitative change that the i.e. first predetermined threshold value is corresponding Being 2, when i.e. the displacement of first object is more than the first predetermined threshold value, cursor moves 2 default grids on the display screen.

Further, after terminal receives the second operational order, if user determine cursor to target location away from From during less than the second predetermined threshold value, user can control terminal and reduce the predetermined number that the first predetermined threshold value is corresponding, and then when the The displacement of one target is more than the first predetermined threshold value, and cursor moves the grid of the predetermined number after reduction on the display screen, I.e. when the displacement of first object is more than the first predetermined threshold value, the distance of corresponding cursor actual movement on the display screen Diminish, light can be prevented effectively from and be marked on default grid and move past target location or mobile fall short position, it is achieved that work as light When distance between subject distance target location is not the unit length of integral multiple, the most close between cursor and target location.

Further, after terminal receives the second operational order, if user determine cursor to target location away from From during not less than the second predetermined threshold value, user can control terminal and increase the predetermined number that the first predetermined threshold value is corresponding, and then works as The displacement of first object is more than the first predetermined threshold value, and cursor moves the grid of the predetermined number after increase on the display screen Lattice, i.e. when the displacement of first object is more than the first predetermined threshold value, the actual movement on the display screen of corresponding cursor away from Big from becoming, and then cursor quickly moving to target location can be realized, improve the user operability that cursor moves.

In the embodiment of the present invention, user can regulate the first predetermined threshold value according to the how far of cursor distance objective position Corresponding predetermined number, and then the distance that cursor corresponding to the displacement that realizes regulation first object moves on the display screen Size, it is achieved the most close to target location of cursor, improve accuracy and the operability of user that cursor moves；Phase For prior art, presetting of the grid moved on the display screen by the cursor that the displacement of regulation first object is corresponding The size of quantity, it is achieved that when the distance between cursor distance objective position is not the unit length of integral multiple, cursor and mesh The most close between cursor position.

Step 107: receive the first operational order.

Concrete, after terminal changes the size of predetermined number corresponding to the first predetermined threshold value, if again receiving use On the default grid that instruction terminal shows in its current display interface after mobile light target the first operational order, again open Begin to detect displacement and the moving direction of first object, when determining the displacement of first object more than the first predetermined threshold value Time, along the moving direction of first object, cursor is moved on the display screen the grid of the predetermined number after changing size, its In, this grid size is constant, will be marked on the default grid of first resolution the grid moving predetermined number by light；And then according to The displacement of first object and moving direction, be marked on light on the node of default grid of first resolution, from the second position Move to the 3rd position.

Further, after terminal reduces the predetermined number that the first predetermined threshold value is corresponding, if again received for referring to Show after moving light target the first operational order on the default grid that terminal shows in its current display interface, start again at inspection Survey displacement and the moving direction of first object, when the displacement determining first object is more than the first predetermined threshold value, Along the moving direction of first object, cursor is moved on the display screen the grid of the predetermined number after reduction, wherein, this grid Size is constant, will be marked on the default grid of first resolution the grid moving the predetermined number after reducing by light；And then according to The displacement of first object and moving direction, be marked on light on the node of default grid of first resolution, from the second position Move to the 3rd position.

The process that specifically performs of step 107, is referred to step 103 and the step 104 of above-mentioned steps, the embodiment of the present invention It is not repeated at this.

Further, this terminal can also accept the 4th operational order, and wherein, the 4th operational order is used for indicating terminal to close Close grid display function, i.e. cancel the display of the default grid of current display interface, or cancel presetting of current display interface Grid and light target show.The 4th gesture that 4th operational order is made by terminal recognition to user triggers, and can be prevented effectively from Physical contact between doctor and terminal, meets the sterility requirements of medical operating scene.The concrete gesture form of the 4th gesture Can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.Such as, the 4th gesture Can be to rock two fingers or the palm opened becomes gestures such as clenching fist, certainly, be merely illustrative of herein, do not represent this The second gesture of inventive embodiments is confined to this.

Such as, based on the example above, after moving the cursor to target location, in order to avoid grating image is to liver figure Blocking of picture, user can make the 4th gesture in the range of the gesture identification of terminal, then this terminal can be cancelled current aobvious Show that default grid and the light target at interface show.

In sum, providing the gesture of three types in the embodiment of the present invention, first kind gesture includes first gesture, For triggering the first operational order, it is achieved light is marked on the movement on default grid；Second Type gesture includes second gesture, is used for Trigger the second operational order, it is achieved change the size of predetermined number corresponding to the first predetermined threshold value；3rd type gesture includes Three gestures and the 4th gesture, show function on/off grid.By providing the identification of three types gesture with corresponding Operation rules, can be quickly and accurately positioned target location by cursor.Being additionally, since cursor can only be at the grid of grating image Move between node, thus limit the degree of freedom that cursor moves so that cursor can lock at grid node, without along with The fine jitter of user's hand deviates.

It should be noted that for the gesture of above-mentioned three types, the gesture of condition, the present invention can be met by requirement definition Embodiment only being advised, gesture form is action gesture obvious, unambiguous, and does not limit the concrete form of each gesture.Also That is, in the embodiment of the present invention, the micro-gesture in correlation technique can be replaced by the biggest gesture of action, such that it is able to reduce The identification difficulty of terminal, improves the operability of user, and replaces the full freedom in correlation technique with the cursor of restraint of liberty degree Degree cursor, such that it is able to improve accuracy and the efficiency of cursor positioning.
